For the past 2 days or so, I have had a really strange issue with firefox.

I switch between multiple windows of firefox a lot, copy pasting things. Sometimes it will randomly start adding a "Delay" to the clicking in a new window.

I'll switch to a window, and have to wait a second or 2 before I can click. It's not lagging per say, the tab loads up instantly as usual, but If I click immediately nothing happens.

The really strange thing is, if I click before that buffer, and keep clicking, it still wont register any clicks until I stop clicking and wait for the second or 2.

It's really obnoxious... I do this stuff fast, so the delay drives me crazy.

Sometimes the windows are fine and this doesn't happen at all, but once it does happen, I need to close the window, and reload them to make it stop.

I haven't downloaded any addons, and nothing I know of has changed.

Any ideas?

Asking again: how do you switch (by clicking in the tab, by using a shortcut key or...?)
The reason of the delay is ClearClick protection against timing attacks, but shouldn't kick in if you switch by clicking on the tab or by built-in shortcut keys (otherwise it's a bug and I'd like to investigate it).
That's why I'm asking.

i use mouse click in the tab to switch.

posiable to disable ClearClick protection ?

You might uncheck the boxes on the bottom of the NoScript Options|Embeddings panel.
BUT I strongly discourage that: I'd prefer you to help resolve the issue, in case someone else has the same.
I couldn't reproduce it yet: if I click on a different tab and paste (ctrl+v) or focus a text box quickly, the action is correctly carried on.
This makes me suspect an extensions conflict: does this problem happen also in a clean profile with just NoScript installed? If it does, could you give me step-by-step instructions to reliably reproduce it?
Finally, a suggestion: update to Firefox 19.0.2, it contains several security fixes.

Funnily enough, recently, some work was done (don't remember which version it landed) to improve exactly this (tab switch delay) in vanilla Firefox.

Not exactly this. If I understand the problem correctly, the tab switches instantaneously but you can't interact with the content before 800ms. Still, it shouldn't happen if you switch by "normal" means, i.e. by clicking on the tab or using the built-in shortcut key combo.

i will record a video to show you.
